In economy seating, what is stated about oxygen masks per seat group?

• A. Each seat group has one extra oxygen mask
• B. Each seat group has two masks
• C. No extra masks per seat group
• D. Masks are only in the front row

Answer: (A)

The idea being tested is redundancy in the oxygen system setup. In economy seating, groups of seats are treated together for safety equipment counts, and there is one extra oxygen mask in each seat group beyond the number of passengers in that group. That extra mask provides a spare in case a mask is missing, damaged, or couldn’t be counted correctly during checks, ensuring there’s always a mask available for everyone in that group. Oxygen masks are situated above every seat, not just in the front row, so it wouldn’t make sense to say there are no extras or that extras are only up front. The single extra per seat group is the standard way to maintain readiness and quick access across the cabin.
